Fir & TV Size Guide

Ideally, we think the fire should be slightly bigger than the TV. But there are no rules! Your fire can be smaller than the TV, the same width, or wider, and still look stunning.

Description

Dimplex Cassette 1000 Project Multi Optimyst Fire

The Dimplex Cassette 1000 Project Multi uses patented Optimyst technology, combining cold water vapour with multicolour LED lighting to create an open, three-dimensional flame effect visible from every side. It can be used alone or linked with compatible cassettes to form a longer line of fire for media walls, see-through fireplaces and custom installations.

Control flame intensity, colour and the adjustable crackling sound from the included remote, the controls on the cassette or the Flame Connect app. This is a flame-effect-only appliance and does not include a heater.

Please note: a contemporary metal plate is supplied. A log-effect fuel bed is not included; an optional premium oak log set is available separately.

About Dimplex

Dimplex is one of the most recognised names in electric fireplaces, with a heritage spanning more than 70 years. Renowned for innovation, quality and reliability, Dimplex has helped shape the modern electric fire industry through the development of some of the world's most realistic flame technologies. Today, Dimplex fireplaces can be found in homes, apartments, hotels and commercial spaces across the UK and around the world.

As part of the Glen Dimplex Group, one of the world's largest manufacturers of electric heating products, Dimplex continues to invest heavily in research, product development and energy-efficient technology. This commitment to innovation has enabled the brand to remain at the forefront of the fireplace industry while helping homeowners enjoy the ambience of a real fire without the complexity of traditional wood-burning or gas appliances.

Pioneers of Electric Fire Technology

Few fireplace manufacturers have contributed more to the development of electric fire technology than Dimplex. The company has introduced several industry-leading flame effects that have transformed how electric fires look and perform.

Dimplex Optiflame® technology has become one of the most recognised electric flame effects in the world, creating realistic flames and glowing fuel beds without the need for a chimney or flue. The company later introduced Optimyst®, a revolutionary system that uses ultra-fine water vapour and lighting effects to create the appearance of flames and smoke. Dimplex also developed Opti-V®, combining high-definition visual effects, glowing logs and authentic crackling sounds to create an incredibly immersive fireplace experience.

Designed for Modern Living

Dimplex fireplaces are designed to complement contemporary lifestyles and modern interior design. Whether you're creating a media wall, installing a panoramic feature fireplace or adding warmth and atmosphere to a living room, Dimplex offers a wide range of solutions to suit every home.

Many Dimplex electric fires can be enjoyed with or without heat, allowing you to create a cosy atmosphere throughout the year. Energy-efficient LED technology helps keep running costs low while delivering vibrant flame visuals and impressive realism. The flexibility of electric installation also allows Dimplex fires to be incorporated into spaces where traditional fireplaces would not be practical.

Innovation Meets Sustainability

As the demand for more sustainable home heating solutions continues to grow, Dimplex remains committed to developing products that reduce reliance on fossil fuels while maintaining the comfort and atmosphere people associate with a fireplace. Electric fires offer an environmentally conscious alternative to traditional fireplaces, providing visual enjoyment without emissions from combustion inside the home.

For a LIMITED TIME ONLY, all of our fires now include FREE SHIPPING to mainland UK. If you live in a special class area, such as some parts of the highlands, you may be required to pay an additional fee. We will contact you if this is the case.

Delivery Information

We offer a nominated day delivery service on many of our products. Where this is selected, we will always do our best to meet your chosen date. For example, if you select a Tuesday delivery, we will typically dispatch your order on a next-day service the working day before.

However, once your order has left us and is with the courier, delivery is handled by a third-party network. While we work closely with our carriers, we cannot be held responsible for delays caused once the goods are in transit.

Deliveries are made on a kerbside basis only. This means the driver will unload the goods as close to your property as safely possible, but they are not insured to carry items into your home or unpack them.

Due to the nature of pallet deliveries, access must be suitable for large vehicles and pallet trucks. If you have any access restrictions, please let us know in advance.

Important: We strongly recommend that you do not book installers, fitters, or any other tradespeople until your goods have been delivered, as delays can occasionally occur.


Returns Policy

We accept returns on items that are:

  • Undamaged
  • Uninstalled
  • In their original packaging

Please note that return costs are the responsibility of the customer.

If required, we can arrange a collection on your behalf, however this service is chargeable.
